my boyfriend's cousin passed away they're having the viewing today, it's like 3 hours long I told his family I'll go of they want me to because I wasn't close to him but I'll be there to support them, they want me to go but how the check do I keep Sophia quiet? I feel it's definitely not a place for a baby.
